Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Area of Science:

  • Pulmonology
  • Clinical Assessment Tools
  • Health Services Research

Background:

  • The Asthma Control Test (ACT) is a widely used tool for assessing asthma control.
  • Existing tools may not fully capture the nuances of asthma control within specific sociocultural contexts.
  • Adaptation of international health instruments is crucial for accurate patient assessment in diverse populations.

Purpose of the Study:

  • To evaluate the utility and feasibility of customizing the Asthma Control Test (ACT) for Korean patients, creating a Korean Asthma Control Test (KACT).
  • To develop a culturally relevant diagnostic tool for assessing asthma control in South Korea.
  • To identify items with the greatest discriminating validity for the KACT.

Main Methods:

  • A survey of 392 asthma patients was conducted using 19 items selected for their relevance to the Korean sociocultural context.
  • Guideline ratings were integrated with specialist evaluations.
  • Stepwise regression analysis was employed to select the most effective items for the KACT, focusing on discriminating validity.

Main Results:

  • KACT scale scores demonstrated significant correlations with integrated ratings (r=0.77), specialist evaluations (r=0.54), and FEV(1) percent predicted (r=0.39).
  • Integrated ratings identified 34.3% of patients as well-controlled, contrasting with higher percentages identified by specialist (56%) or guideline ratings (48.6%).
  • The agreement between KACT and integrated ratings varied from 45% to 78%, depending on the chosen cut-off points.

Conclusions:

  • It is feasible to create a valid and useful country-specific diagnostic tool for asthma assessment by adapting the original ACT.
  • The KACT effectively reflects differences in sociocultural context, improving asthma control assessment for Korean patients.
  • The developed KACT provides a culturally sensitive instrument for evaluating asthma control in South Korea.
